THE WAY TO DEVELOP CONDITIONAL REFLEX IN PIGS

Abstract

One of the biologic characteristics in pigs housing is the arrangement of «lavatory» in a strictly certain place where it is wet, dark, but what is most important there must be the possibility to contact other animals from the neighboring stalls. The examinations showed that defecation places designated and the lateral wall made next to the automatic drinking trough encouraged fewer defecations in the first zone (lair) in the experimental group as compared to the control. This was observed in the first three days of monitoring. It was established that in the first zone, the second and third experimental groups defecated by 2.38 and 4.2 % less in number; in the second (feeding) zone, they did it by 6.6 and 15.5 less, but it was otherwise in the third (defecation) zone where they defecated by 8.3 and 19.7 % more. Ten days later, the amount of animal wastes in the first stall did not change notably. The highest number of defecations was observed in the second (58.9 %) and third (30.5 %) zones. No defecation was marked in the second stall in its first zone; as for the second zone, defecations made up 16.2 %, but the third zone was noted to have the highest number of defecations (83.2 %). The analogous regulation was marked in the third stall. No defecations were found in its first zone, in the second one they were 10.5 % and in the third - 89.5 %. The defecation places designated and the lateral wall of the stall made next to the automatic drinking trough also allowed to decrease aggression responses in pigs in the second zone by 33 and 60 %, in the third - by 75 and 100 %, respectively.
